Add temporary project ID support for safe outputs

[Copilot]

Safe outputs execute async in a separate job, so agents calling create_project never receive the project URL needed for subsequent update_project calls. This broke campaign generation workflows where field creation requires the project URL.

Changes

MCP server handler (safe_outputs_handlers.cjs)

• New createProjectHandler auto-generates temporary ID if not provided
• Returns {result: "success", temporary_id: "aw_...", project: "#aw_..."} to agent

Tool schemas (safe_outputs_tools.json)

• Added optional temporary_id field to create_project
• Updated update_project.project pattern to accept temporary IDs: ^(https://github\.com/...|\#?aw_[0-9a-f]{12})$

Project handler manager (safe_output_project_handler_manager.cjs)

• Builds temporary ID → URL map as messages process
• Stores mapping after successful create_project: map.set(temp_id, projectUrl)
• Passes map to subsequent handlers

update_project handler (update_project.cjs)

• Resolves temporary IDs to actual URLs before processing
• Supports both #aw_abc123def456 and aw_abc123def456 formats

Usage

// Agent workflow (automatic)
create_project({title: "Campaign"})
// Returns: {result: "success", temporary_id: "aw_abc123def456", project: "#aw_abc123def456"}

update_project({
  project: "#aw_abc123def456",  // Resolved during safe_outputs job
  operation: "create_fields"
})

Pattern matches existing issue temporary ID system (temporary_id.cjs).

Original prompt

Analyze campaign generation run: https://github.com/githubnext/gh-aw/actions/runs/21235852123
Understand and fix why:

• Update project did not take place (to add fields like new status item, worker workflows, etc.)
• Update issue did not work (no updates to the issue body)

@copilot This should not affect other update-project safe output calls outside of the campaign context.
